Okay, so you're the mysterious Curse.
Your first question is probably, "what exactly am I?"
Answer: the Curse is the influenza virus.
Although today people are often dismissive of "the flu,"
And your job is to make South Spratly Island a fertile
What do you do?
WHAT YOU DO:
You want to get each strain out of its reservoir and spread it into as many populations as possible. (Each group of humans or animals in a village represents a "population.") If a strain "shifts," it's even possible for you to jump the interspecies barrier and have the Swine flu infect humans, for example.
INTRODUCING: YOUR WORKSHEET
WHILE THE GAME GOES ON,
You need to keep track of each "corridor of transmission"
for your strains.
Now start your three flu strains moving! Move each flu
strain along all
For example, the Avian Flu Strain emerges from the Avian reservoir and moves down Avian corridors to any village that successfully hunted ducks. The Swine Flu Strain emerges from the Swine Reservoir and moves down Swine corridors to any village that successfully hunted boar. The Human Flu Strain enters the Hotel if it has guests this year (tourists bring flu to the island) and moves down any corridors created by villagers working at the Hotel.
If there is a suitable population at the end of the corridor,
now see if you can infect it!
If you do infect that population, you can follow any additional corridors that lead onward from that population. For example, let's say Village A sent workers to the Hotel, and Village B traded with Village A. The Human Flu strain that comes into the Hotel would move down the corridor that the workers created between the Hotel and Village A. You draw a card from the Transmission Deck, and it is black - so now the human population of Village A catches the flu. So now the human flu moves down the corridor created by the traders between Village A and B, and tries to enter the human population of Village B. You draw a card from the deck, and it is red. You are not successful at infecting the Village B humans - this corridor is a dead end (although you might get to Village B through some other corridor).
As you go, record which populations you infect (and with how many different strains). Each infected population will suffer some deaths, based on the virulence of each flu strain that infects it. You'll have to tell this to the village at the appropriate time (when the villages are figuring Births and Deaths).
You should move all the flu strains you can as far as they can go, and figure out which populations you infect successfully. Then it's time for Drift and Shift. This is an exciting time for the influenza virus!
"Drift" is when a flu strain evolves slightly - it may become more or less virulent. "Shift" is when a flu strain evolves enough to jump the interspecies barrier and move into a new animal population.
For each population you successfully infected, draw a Drift n' Shift card. If the card is black, there is no Drift or Shift. If it is an odd-numbered Red Card (5, 7, 9), then the flu strain has shifted and become more virulent (virulence rating +1). If it is an even-numbered Red Card (6, 8, 10), then the flu strain has shifted and become less virulent (virulence rating -1). Apply this new virulence to the flu's effect on this population and any populations "downstream" from this one.
If the card is a Red face card (K, Q, J) the flu strain has Shifted! You create a new flu strain in this population, which can try to spread along transmission routes all over again. If this population is in a village, the Curse can jump this new flu into a different animal population and also try to spread it out from there. This new flu strain has a virulence rating of +1 over the old strain. You draw a Drift and Shift card for each population infected by the new strain as usual.
If the card is a Red Ace, the flu strain has Shifted, as above, except the virulence rating of the new strain is +2 over the old strain.
All this may require careful bookkeeping. Take your time
and do it carefully.
Here's the virulence chart for flu.

Q: How mysterious should you try to be?
A: You should be as mysterious as possible.
But try to let them figure out the identity of the Curse for themselves!
